Referring ncrv, to. the j drawings 1 in, detail, `the numeral 1 clesignatesya trueln In the present instance, the` truck is .mounted on `Wheels 2. Vllhen properly arranged in a field or other, place vfor receivinga load on the elevator, supported by there. truck and hereinafter to be ..descr,ibed the, Wheels, 21 are blocked to prevent` the accidentali turning thereof andthe consequent movement ofA the truck.A S5

,suitably supported at anupivardinclinationen; the body oi? the truck l is .an elevater-3.- Theelevator proper is` arranged between side boards 4C', the elevator being being arranged yaround rollers Zirespectively that arerkeyed or otherwise secured to shafts .8 and 9= respectively. In addition to the shaftsSlandQthereiis another shaft 10= disposed a slight distance abovefthevshaftQ `and arranged between the leads,y of theeleyator. This shaft, as Well Aas the upper shaftr 8 have vkon their ends, sprocket wheelsll and 12 respectively, and around these. sprocket Wheels are trained sprocket chains 13 re. spectively. In addition to.v the sprockets ontheloxvershaft l() there. are secured other sprockets 1li.Ak respectively, and` around-'these last mentioned sprockets there are;A trained endless chains l5 respectively which are alsotrained around sprocket Wheelszit) respectively that are secured on a shaft 17 arranged transversely ot the :trame or bodyfof I the truck l and journaled` in suitable bearn the truck, there are drums 31 ings 18 respectively. On the shaft 17 there are keyed toothed wheels 19 respectively and meshing with these wheels 19 are pinions 2O respectively secured upon a counter shaft 21 journaled in bearings 22- on the frame or body of the truck 1. The counter shaft has secured thereon a pulley wheel 23.

around which is trained an endless belt 24 which is also trained around a pulley 25 on the drive shaft 26 of a motor 27 which latter is suitably supported on the frame or body of the truck 1. It Vwill thus be apparent that when the motor is in action the counter shaft will be turned which will impart motion to the inain shaft 17 and the latter through the medium of the sprocketJ chains connected to the sprockets on the shaft 10 will operatethe sprocket chains 13 to cause the operation of the elevator. The shaft of the motor turns only in one direction, so that the upper lead of the eleva- -tor always travels in an upward direction.

Between the side boards, at the receiving end of the elevator there is a downwardly inclined lip board 28 on hereinafter to be described will travel, and on the lip board there is a contact strip 29 against which the inneror forward end of the scraper will contact to permit of the tilting of the scraper by means presently to be described and to deliver the load therefrom on' to the elevator. Therload thus received will, of course, be raised to the rear of the truck 1 and be delivered through a suitable chute 3() to a wagon or like conveyance arranged below the truck. the load may be arranged in a pile or stack at the rear of the truck.

Freely mounted on the main shaft 17, outward of the sprocket wheels 18, and consequently outward with respect to the sides of and 32 respectively. On the outer side or face of each drum there is a clutch surface 33 and 34 respectively. The cuter ends of the shaft 17 are received in and keyed or splined to bearings 35 respectively which are in the nature of tubular members and which have their inner faces provided with clutch surfaces 36 'and 37 respectively. The-tubular clutches 35 are arranged for revoluble but held against longitudinal movement in members 37 that L are pivoted, as at 38 to brackets 39 which extend outwardly from the sides of the truck. The opposite ends of the members 37 are pivoted, as at 40 to rod or bar 40 with `respect to the truck,

which is, of course, arranged transversely and the said rod is provided, adyacent to one of its ends with 'an offset operating` handle or lever 41. Se-

cured to and wound around the respective drums 31 and 32 are cables 42 and 43 respectively. The cable 42 is directed around sheave wvheels 44 and 45 lrespectively which fare loosely ysupported by stakes 46 and 47 rewhich the scraper,

If desired, f

spectively that are driven into the ground at the place where the load is to be received, such place being disposed a considerable distance away from the truck andV elevator. The sheave wheel 44 is in a line with the drum 31, and the sheave wheel 45 is in a line with the longitudinal center of the elevator. The free end of the strand or cable 42 is secured, as at 48 to a bail 49 on the rear end of a scraper 50. The scraper is in the nature of a material gathering element and while the same, in the showing of the drawings is illustrated in the nature of a slidable fork, it is to bennderstood that if desired the gathering element may be otherwise con structed. The scraper 50 has its sides provided with upwardly extending handles 51 arranged at the rear thereof, while its said ywheels and is directed toward the scraper and secured to the center ofthe bail 52 thereof.

As previously stated, the strands or cables 42 and 43 are wound around therespective drums 31 and 32, and also, as previously stated, the main shaft 17 revolves always in one direction. Thus by operating the handle 41 to move the rod 40 to bring the clut-ch element 37 in engagement with the clutch element 34 on the drum 32 the clutch surface 36 will be brought away from the clutch surface 33 on the drum 31, the clutch sleeves, being splined or keyed on the shaft 17. Thus the drum 31 is freed frorn'the shaft, but the drum 32 is locked thereon and will turn to wind the cable 34 thereon. The winding' of the cableV 34 draws the scraper or gatherer 50 towardV the elevator, causing the saine to travel over the lip board` 28 and to engage with the contact strip 29, a further drawing on the said cable causing the tilting ofthe gatherer or scraper s0 that the load therefroinwill be deposited on to the elevator. In the meantime the strand or cable 42 is unwound from the drum 31. Then the scraper is to be returned for another load, the handle or lever 41 is operated in a reverse direction, causing the clutch surface 36 to engage with the clutch surface 33 on the drum 31 and bringing the clutch surface 37 to engage with the clutch surface 34 on the drum 32. This frees the drum 32 from the shaft but moves the drum 31 thereon and the turning of the said drum' 31 will iso cause the cable 42 to be wound therearound, and' such movement of the cable will, of course, cause the scraper or gatherer to be moved outwardly away from the elevator.

It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction, opera-tion and advantages of the im provement to those skilled in the art to which such inventio-ns relate, and it is thought necessary to add that the showing and description refer only to a satisfactory embodiment of the invention as it now appears to me and that I may make such Y changes therefrom as fall within the scope of what is claimed.

Having described the invention, I claim In a loader, a wheeled support7 laterally disposed brackets extending from a sup-port, bearing members pivotally secured thereto at their outer ends thereof, a shaft transversing the support and mounted for rotation in the bearing members, means for roe tatng said shaft, a drum mounted for free rotation on each end of the shaft, a clutch member 'on each drum, a clutch member on each bearing member cooperatively associated with the clutch members of the drums, a bar transversing the support and having its ends pivotally secured tothe bearing members, and means for moving said bar transversely for operating the drums as and for the purpose specified,

In testimony whereof I aflix my signature.

MIKE BERG.
